To all whom iigmay concern:

'Be it kiiown hai; 1, JOHANNJES Timonos Peimusiiis. a citizen of the United States, re siding at Flushing, iii the borough of Queens, city and .Siaee of l. York, have invented. an improvement in Rubric? in i of which the following I e My present invention lubricating gesolene engines, of a. mined typ and used in conjunction ille cam shaft for operaiing the vawes an ignition zin er o l the shaft as err: ioyed such. engines.

Herecofore, in the use vices, as applied gas engines-in motor carriages, it has been usual to employ one or more sight feed devices arranged in View of the diver on the dash board or placed otherwise so that they may be readily seen, together with apparatus for forcing-she oil to the sight feed devices and conveying the same away from these devices to the parts This, as will be understood, necessitaeed i'elaiively long lengths of pipe and consequently increased the cost of the lubricating apparatus and its operation,

as well as the liability of the same he become deranged.

The object of rov present invention is to provide a lubricating apparatus associated with the casing of the engine, wish which the same is employed, in such e. manner that the lubricant is preferably forced by a pump, or similar 6" ice actuated from 'the cam shafi, into a sight feed from which the oil is con":eyed to the en ine parts to he lubricated through a means 20:: securing the oil cup in position on the en and also to provide asimpl connection between pump shaft so readily sepals-ate The design e proved luhiicafiieg adap' zed Oil 01' i'emal'ter illOYE paiatus will ola'rly described.

In the drawing. of my improved Fig.2 a. is same, section sight :fe lubricant sure is an. elevation to she pump sl "11g, 10 indicates the head of ing, which, on ls 'aez'iphery, oies through are passed secure the head in 'o 0;. these beiog shown The I the cam whlch s rovided f 1 suiishle conacts for making connection. successively with the iermina'ls 1%, and fromjhe same to she spark plugs of the several cylinders of the engine.

The end of the cam shaft is indicated at 15. This, as shown, is screw threaded, and thus adapted to receive a nus 16. This nut is preferably provided with a beveled end, extending across the bore of which, shown in Fig. 2, there is a pin 1?.

18 indicates a rotary pump, of any desired construcfiioh, the shaft of which is indicated at 19, and at its inner extremity is sloited at 20, in order to recei e the pin 17 of the nut 15.. The supply pipe 21, l ading from suiiablc reservoir, is connecied so the suction end of the puI-np l8 and. discharge pipe is coniiecied a5; the discharge or outlet end of and at its opposite o ii feed or oil cup device, which pieieehly comprises e. base 523, glass cylinder 2%, and a cap 25, she discharge pipe 22 leadin in a suitable manner to [i the Oll oiher lubi'icm i. tiniinterior oi -e sight feed device, a2 d as i Lil. also he understood, this d scharge may be controlled a suitaole valve regulated by an use: 526, or' otherwise.

i Wiz'Lh a col Ii the head 10, and is turned dowuiif o a tap ed opening provided he head 16, and also iereioi' in ah infl' *0 which the head is s The has wed. l the sight feed cup is *ferahly cylindrical, and at the opposite ends thei'eof there, are washers 28 and 29,

in order to insure mailing tight joints between the arm 33 and the bosson the oil Well and the cylindrical base of the sight feed cup.

in a predetermined position, the bolt 27 is of reduced diameter, as indicated at 31, this reduced portion coining immediately below the central outlet or discharge port in the sight feed cup, and the bolt is-also recessed longitudinally, as indicated at 32, so that the 01! passing from the cup may run into the recessed portion 31 and through the groove 32, irrespective of the position which the bolt may assume after the same has been turned to place, in order to permit the oil or other lubricant to be supplied from the cup through the recess and groove in the bolt to the oil well and through an aperture 3-iin the head 10 to the parts of the engine to be lubricated.

Referring to Fig. r, it will be seen that instead of employing the connection hereinbei ore described, between the cam shaft and the pump shaft, 1 may make the inner end of the pump shaftsquare, as indicated at 35, or of any number of sides, as will be ap parent, and make an aperture inthe end of the nut 16 to receive the square or other shaped end of the pump shaft in order that these parts may be positively connected and yet easily separated.

I claim as my invention: 1. in a gas engine and in combination with the head of the casing thereof and an ignition timer, a shaft for operating the engine 'alves and the timer, a pump driven by the shaft, an oil cap, a connection between the discharge of the pump and the said oil cup, and a device for securing the said oil cup in position, by which the oil is conveyed therefrom to the parts to be lubricated.

in a gas engineand in combination with the head of the casing thereof and an ignition timer, a cam shaft for operating the engine valves and ignition timer, an oil pump, a connection between the cam shaft and the pump shaft, whereby the pump is driven from the cam shaft, an oil cup, a connection from the pump discharge to the oilcup, and a device for securing the oil cup in position and conveying the oil therefrom to the parts to be lubricated.

3. In a gas engine and in combination with the head of the casing thereof and an ignition timer, a cam shaft for operating the engine valves and the ignition timer, an oil pump, a shaft therefor extending into the timer case, and at its end slotted therein, a nut secured on the end of the cam shaft, a pin fixed transversely in the end of the said nut and adapted to receive the slotted end of the pump shaft, an oil cup, a connection between the discharge of the pump and the said oil cup, and a device for securing the oil cup in position and conveying the oil therefrom to the parts to be'lubricated.

at. In a gas engine and in combination with the head of th casing thereof and an ignition timer, a shaft for said ignition tin er, an oil pump, a shaft therefor extending into the timer case, and at its end slotted therein, a nut secured on the end of the timer shaft, a pin fixed transversely in the end of the said nut and adapted to receive the slotted end of the pump shaft, an oil. cup, a connection between the discharge of the pump and the said oil cap, a. bolt pass ing through the base of the oil cup and se cured in the said head of the engine casing to maintain the oil cup in position, the said bolt being provided with a circuniferentially grooved section and also with a longitudinal groove, whereby .the oil from the cup may be conveyed therefrom by the bolt to the parts to be lubricated, irrespective of the position assumed by the bolt when turned down to place.

Signed by me this 10th day of February, 1915. I
